pureLiFi, the light communications technology company, that transmits data using light waves from ‘off-the-shelf’ LED bulbs, says they have doubled the previous levels of data rates. Li-Fi enables energy-efficient data transmission using LEDs in light fixtures.
pureLiFi demoed the world’s first commercial Li-Fi product, Li-1st, during March at MWC 2014 and CeBIT 2014.
“At the Li-Fi centre in Edinburgh, we’ve established that we can still transmit data wirelessly at data rates close to 100 per cent when lights are dimmed to levels where they appear to be switched off altogether.”
“This latest development furthers the case for Li-Fi revolutionising wireless communications, helps keep pureLiFi at the forefront of research and commercialisation and shows that Li-Fi really could be the enabler of the Internet of Everything.”
Medical engineers said Sunday they had created a device the size of a plaster which can monitor patients by tracking their muscle activity before administering their medication.
Methods for monitoring so-called "movement disorders" such as epilepsy and Parkinson's disease have traditionally included video recordings or wearable devices, but these tend to be bulky and inflexible
The new gadget, which is worn on the skin, looks like a Band-Aid but uses nanotechnology—in which building blocks as small as atoms and molecules are harnessed to bypass problems of bulkiness and stiffness— to monitor the patient.
Scientists have long hoped to create an unobtrusive device able to capture and store medical information as well as administer drugs in response to the data.
